Today only, and for just the first 10,000 signups, you can get a $79 annual membership to ShopRunner for free. This gets you unlimited 2-day shipping at a bunch of stores like NewEgg, Drugstore.com, Toys R Us, Fog Dog, and more.

Similar to Amazon's Prime Membership, but for other web stores, a ShopRunner membership also provides another useful feature: free return shipping. So hit up the link below before it's too late. (Note: Your membership will be renewed automatically after a year, but you'll be notified before your credit card is charged. You could also use a virtual credit card number to avoid the recurring charge.)
